The PCT Process: An Overview
The PCT procedure is divided into two main phases: the international phase and the national/regional phase.
1. International Phase: The applicant files an international application with a competent receiving office, which is then subjected to an international search for prior art and an optional preliminary examination. In an International Search Report (ISR), the results are compiled along with a written opinion on the patentability of the invention.
2. National/Regional Phase: Following the international phase, the applicant can pursue patent protection in specific member states by entering the national or regional phase. This involves fulfilling the requirements of each jurisdiction where protection is sought, typically within 30 or 31 months from the priority date.
